Will the Reese Goose Box RP94720 Fit a 2021 Keystone Cougar 364BHL?

Question:

I have a 2021 Keystone Cougar 364BHL fifth wheel. I am looking to switch to the Reese Goosebox and am wondering if it needs a spacer kit or fits as is. Where can I find which frame my fifth wheel has? Thanks in advance.

Installing a Reese Goose Box is definitely a popular upgrade. That being said, the # RP85FR is specific to the Lippert 1621 and 0719 pin boxes, so you will need to confirm your pin box before purchasing.

Your specific pin box number can easily be verified by contacting the manufacturer of the trailer. All you will need is the VIN and they should be able to tell you as they keep this on file. This is always my first suggestion as it is by far the easiest and quickest way.

In the off chance they cannot tell you, however, there are other ways to verify which one you have. First will be to check your pin box for a label. The manufacturer and model number of the pin box is usually printed on a sticker or stamped into a plate or directly into the metal of the pin box.

If the label has been removed and no stamping can be found, you can also measure to confirm you pin box number. I have an article attached that will show exactly where to measure and what that measurement will determine.
